Segura Viudas, in particular, is one of Freixenet's brands that offers even more bubblies. In my opinion, SV's Brut Reserva is a better value than Cordon Negro. Segura Viudas also offers Aria Brut Nature. It's priced around ten dollars. Aria is still very much a Cava - yet it seems to be slightly more nuanced than the typical Cava.
